We have a spin-one-half projectile (mass m, Energy E = ℎ 2

2

ଶ

). This projectile scatters

a spin-one-target of infinite mass.

For this, the Hamiltonian is:

∫ = ଵଶ

−

In the above expression, µ > 0, σi represent the Pauli spin operators, where for i=1,

we have the spin operator for projectile and for i=2, we have spin operator for

target.

Evaluate ௗ

ௗΩ

(differential scattering cross section), in lowest order Born

approximation. The same should be calculated as a function of k and scattering

angle. Also, computation should be done averaging over initial; and summing over

final states of spin polarization.

Asmall, positively charged ball is moved close to a large, positively charged ball. which describes how the small ball likely responds when it is released? it will move toward the large ball because like charges repel. it will move toward the large ball because like charges attract. it will move away from the large ball because like charges repel. it will move away from the large ball because like charges attract.
